Block 15 is divided into two distinct blocks, Block 15 (Indillana) and Block 12 (Eden-Yuturi), as a result of changes in Ecuador's hydrocarbon law in 2011. Block 15 is comprised of 13 producing fields. Three distinct producing areas make up these fields: the Indillana Complex, Limoncocha and the Yanaquincha Complex. All fields are fairly mature and in decline. There is production upside through the potential of additional discoveries, infill drilling and EOR.
